Standard Window Profiles in Canada
Whether it’s about installing new windows in the entire property or just replacing a few units, frame profiles always remain the crucial factor that dictates how things should be done. As a matter of fact, every window profile is different from the other, and the decision to select one profile depends on the property’s demand. I.e. some homes need high profile windows while others require low profile units.
As far as the profile status, with respect to the window type, slider hung, and end-vent windows are famous for having low profile frames. Casement and awning windows usually have high profile frames. But, what if the home needs both profiles in the same windows? Picture windows turn out to be the perfect option available in this regard.
If homeowners want to install new units beside the current ones, the following information would be the most useful part of the process. Experts always suggest considering the frame profile and search for the closest match so that everything could be done as it is expected. Another significant fact is that the window profile predetermines the amount of light coming into the home.
Since high profile frames have the low surface area, they do not allow an ample amount of light to pass through, while low profile windows always maximize brightness.
To make this fact more authentic, here is the numeric evidence:
| Dimensions (In) | Low Profile Glazing Dimension (1.5in frame) | High Profile Glazing Dimension (3in frame) | Surface Area Low vs. High (In2) | Percentage Difference |
| 24 x 12 | 21 x 91/8 | 181/16 x 61/16 | 191.63 vs. 111.76 | 71% |
| 24 x 24 | 21 x 211/8 | 181/16 x 181/16 | 443.63 vs. 328.51 | 35% |
| 24 x 48 | 21 x 451/8 | 181/16 x 421/16 | 947.63 vs. 762.01 | 24% |
| 48 x 48 | 45 x 451/8 | 421/16 x 421/16 | 2030.63 vs. 1774.51 | 14% |
| 72 x 48 | 69 x 451/8 | 661/16 x 421/16 | 3113.63 vs. 2787.01 | 12% |
Brickmould, Casing and Jamb Extensions
As mentioned earlier, there are different profiles for all window types and homeowners have to analyze closely in order to come up with the most efficient one. Apart from being concerned about standard window sizes Canada, homeowners also have to realize the importance of the trim or casing that is present around the windows.
Standard sizes usually have a 3 3/8-inch or 2 5/8-inch vinyl casing, but it’s not necessary to consider the same all the time. Homeowners can go for any other option as per the type of a brickmould added. If someone doesn’t know what a brickmould is, it’s high time to get some basic knowledge – it is the seal present in-between the frame and wall to prevent outside elements like air and moisture from entering the rooms. When it comes to removing the existing windows, the brickmould size has to be adjusted to the dimensions of the existing windows.
Jamb extensions are another worth considering part of the windows. They basically work as a frame to fill the gap in the wall at the inner side of the window frame. Its primary purpose is to give that perfect edge and support to the casing. The best part of jamb extensions is that they are available in various sizes, according to the width of custom-made windows. As for the window dimensions, there may be variations with respect to the type.
Nowadays, Direct Pro Windows and Doors suggests installing triple pane windows because of their versatility and durability. But, homeowners should remember that they are smaller as compared to double pane windows. The approach should be to look at the standard window sizes every time before selecting a certain type.
